If someone has only used a handheld wood sander, they will be ecstatic when someone shows them a powered belt sander.

But someone who has used a palm sander, orbital sander, belt sander, disc sander, and so on will be able to see a new type of sander in the context of existing tools and know what’s right for what job.
